There were 41 OCA individuals with missing heritability from these five studies in whom the p.(Ser192Tyr)/p.(Arg402Gln) haplotype was possible, and where the cis/trans phase of the TYR p.(Ser192Tyr) and p.(Arg402Gln) variants could also be determined. This evidence concerns the gene TYR and oculocutaneous albinism.
